To all Lo/wm t may concer/n:

Be it known that l, Ancrrini A'rnrns, a citizen of the United States,residing at Glen Ferris, inthe county of Fayette and State of TWestVirginia, have invented new and useful Improvements in Miners CarbideLamps, of which the 'Eollowingfis a specilication. f d

In carrying out the present 'invention it is my purpose to improve andsimplify the general construction 'ot carbide miners lamps and toprovide a lamp which will embody in its construction, among otherfe'a'-tures, a water receptacle, a carbide receptacle and a gas chamberinterposedfbetween the water receptacle and the carbide receptacle andconnected to the carbide receptacle in.

such manner that the carbide receptacle may be readily Adetachedtherefrom when itv is necessary toreplenish the same, without cuttingofi the flow oit gas from the'k gas chamber to the burner, the gaschamberbeing equipped with a valve by whichcommunication between suchchamber and the atmosphere may be cut ott when the carbidelre ceptacleVis detached' and being also equipped with a hand pump, whereby the gastherein may be placed yunder slightly increased pres sure whenevernecessary or desired.

With the above recited objects in View, and others of a similar' nature,the invention resides in the construction, combination and arrangementof parts set forth in 'and falling within the scope of the appendedclaim.

In the accompanying drawings: l

Figure 1 is a view in side elevation of a carbide miners lampconstructed in accordance with my invention.

lFigure 2 is a vertical sectional view through the same.

Figure 3 is a cross sectional View on the line 3m?) of Figure 2.

Referring now to the drawings in detail, 1 designates a water containerwhich, in the present instance, is circular' in horizontal. crosssection and has its top wallformed with a water inlet opening that iscovered by a cap 2. The side wall of the receptacle 1 is equipped withan outwardly flared hub 3 that carries the lamp burner and ata pointdiametrically opposite the hood 3 the side wall of the receptacle 1 isprovided with a hook 4 by which the lamp may be carried or attached tothe miners cap. y

Below the water receptacle 1 is a lgas chamber 5 which, in the presentinstance, is

circular in f'cross section, as 4shown more clearlyfin Figure?) ofthe^draw1ngslf The i upper end ofthe receptacleis 'reducedl'in diameterand tted into ythe bottom of the receptacle flinorder to' closethelowerend ot the `water receptacle. The bottom' wall 5 of the gaschamber 511s formed with a depending ycircular flange 6. 7 designates alcarbide retainer havingits upper end formed with'an'ext-eri'orlythreaded circular'tlange 8 that engages in the lflange 6, ,so that theupper wend 'of 'the carbide container 7 may be closed' by the bottomwall of the gas chamber Connected to" the top' wall ofthe tacleandextending through the water receptacleand 'the gas chamber `and into thecarbidereceptacle 7 is awater tube9. Adjacent to the bottom of the waterreceptacle 1 the tube 9 is'lr'ormed with an outward openwater receptacle`1| cent'rally ofk 'such recep! ing 10,`and slidably mounted within thetube ,f, 9 andnormally closing the 'outletjopening 10 is a valve v.plug11, connected with the lower end of k,a stem 12 that extends" upwardlythroughthe top of ythe water 'receptacle and is"V equipped yat its upperend with 'arbutton 18. Extending across the water tube 9 below theopening` 10 therein is a pin 14, and interposed between thepin 14 landthe' valve plug 11 isa spring 15. The plug l1 is'for'med with verticalbores 16 through which the water maylow when the plug is depressed bythe button 13 v,against the action of the ,i spring .15 to kuncover theoutlet opening 10,

and when the outlety opening is uncovered the water flows from the waterreceptacle l through the tube y9 into the carbide recep taclelf?,thereby enablingr gas to be generated. in the carbide receptacle. Thebottom wall vof the' gas chamber 5 is formed with a port 17 and on itsupper surfacelat opposite/sides of the port l'this bottom wall isformedf with guides 18 spaced apart in parallelism. Slidably mounted in theguides 18 is a-valve plate 19`formed with a port 2O and provided with astem 21 that extends outwardly' through they `side ywall of the gaschamber andv terminates in a knob 22. f Normallythe Vrport 20A isinalinement with the port 17,` so

that the gas generated by the water and carvbide may flow into the gaschamber 5. From the gas `chamber 5 the gas passes througgghy the tube 28`to ther burner in the hood 3. l

When the 'supply of carbide in the receptacle 7 has become exhausted andit is desired to replenish the same, the valve plate 19 is lmoved'within the guides 18 to close the port 17, thereby enabling the carbidereceptacle to be detached for refilling without permitting the gas inthe gas chamber to escape to the atmosphere. u

Connected to the side wall orthe gas chamber 5 is a pump which comprisesa tube 24 having the portion beyond the gas chamber formed with an `airvent port 25 and its inner endequifpped with an inwardly opening checkvalve V26. TWithiny the tube 24- is avplung'er 27 equipped with a stem28, the outer end or which terminates in a handle 29; By means or thisvconstruction it will be seen that the plunger 2'4" may be manipulated todraw gas into the tube' ik and to force such gas` past the check valve26 into the gas chamber 5, in order to place the gas therein underpressure for maintaining a continuous burning or the flame at the burnerin the' hood While the carbide is being replenished in tank 7 l, I haveentered into a detailed description of theV construction ,and relativearrangementor parts embraced in the present and preferred embodiment ormy invention. with I a view to imparting a full, clearand exactunderstanding` or the said embodiment. l d0 not desire, however, to beunderstood as confining myself to the said speciiic construction andVre'ative arrangement lor parts, inasmuch asin the future practice or myinvention Ysuch ychanges or modifications may be made as fairly railwithin the scope cla-1m.

Having thus described the invention, what is claimed as new, is

A carbide lamp comprising a body having a gas chamber, .a water chamberand a carbide chamber, said chambers being superimposed with relation`to each other, a tube extending from the top wall or the gas chamberand passing transversely through the gas chamber and the water chamberand having its lower end por-v tion received in the carbide chamber withits lower end open and spaced from the bottom or the said chamber, saidtube beor my invention as defined by myappended ing provided at its sideand at `a point 1^ above the bottom oi the gas chamber with an opening,a piston slidably mounted in the tube and provided with openings passingtherethrough, a spring housed within the tube and .confined at one endupon a support and bearing at its opposite endv against the piston andserving to normally holdthe piston in a cosed position over the openingvin the sidey or the tube, and rod connected with the piston and passingthrough the top or the gas chamber, said rod adapted t0 serve as meansfor depressing the piston against, the tension or the springv and torvremoving the piston from over the opening in the side or the tube.
